Okay, I didn’t receive any other comments, so I have removed A10 from the PICS per below. I will forward the updated draft to Keith and request a new poll to publish.
<div>Thanks!<br>

<span>CESG E-Poll Identifier: CESG-P-2014-12-004 Approval to publish CCSDS 766.1-B-1, Digital Motion Imagery (Blue Book, Issue 1) Results of CESG poll beginning 30 December 2014 and ending 16 January 2015:<br>
<br>
Abstain: 0 (0%)<br>
Approve Unconditionally: 2 (40%) (Peccia, Barkley)<br>
Approve with Conditions: 2 (40%) (Shames, Calzolari)<br>
Disapprove with Comment: 1 (20%) (Scott)<br>
<br>
CONDITIONS/COMMENTS:<br>
<br>
Peter Shames (Approve with Conditions): The DMI Blue Book (766x1b1) and the Test report<br>
(760.1-Y-11) are inconsistent and apparently not completely compliant with CCSDS Blue Book criteria. The particular issue is with JPEG 2000 and also with DTN.<br>
<br>
The BB includes sections on JPEG 2000 that are stated as requirements. Refer to the marked up copy attached, particularly Sec 3.4.4.2 and 3.6.1.2. It also includes a DTN section 3.6.3.<br>
<br>
In the YB test report the text explicitly states " JPEG2000 video compression for real-time transmission has not been tested". There is a reference in Sec 4.2 Summary of Tests, in the table, suggesting that JPEG2000 was tested, but this appears to be an error
since there is an earlier statement "no implementations have been made of JPEG2000 in spacecraft and none are currently planned".<br>
<br>
Similarly there does not appear to have been any testing done of DTN for transmission of video streams.<br>
<br>
Conditions:<br>
<br>
1) Remove all normative references to JPEG 2000 from the BB<br>
2) Remove the normative reference to DTN from the BB<br>
3) Align the BB and YB to reflect what has actually been tested<br>
<br>
Alternatively:<br>
<br>
1) Do the testing of JPEG 2000 and/or DTN<br>
2) Align the BB and YB to reflect what has actually been tested<br>
<br>
Erik Barkley (Approve Unconditionally): Comments (but not conditions): The test report offered description of various equipment configurations/connections as the results. It seems that if verification of the proposed referenced industry standards for transmission
of motion imagery were being tested some sort of pre-planned video sequence would have been tested with verification of video as recorded locally and as received remotely would have been good, with some assessment as to color values, aspect ratios, frame rates,
etc being preserved, with respect or test images etc. Perhaps at least a note indicating the design of the test(s) and expected results needs to be added?<br>
<br>
Gian Paolo Calzolari (Approve with Conditions): <br>
Clarify the normative part about transmission over CFDP or over DTN.<br>
Condition limited as SIS AD has already disapproved this publication.<br>
<br>
Keith Scott (Disapprove with Comment): Motion JPEG 2000 and DTN were supposed to be non-normative, but they seem to be normative in this version. I'm pretty sure this is going to require some rework and another agency review.<br>
